Log: Fix bug #61681: Malformed grammar

------------------------------------------------------------------------

This is typically a limitation of our grammar.

We accept ${ string_varname }
and ${ expr }

due to the fact that ${asd} is not accessing the variable named after the 
constant asd's value.

When the lexer looks at ${ function_call() } it finds ${ T_STRING_VARNAME() }

which will not parse. We might be able to fix it by looking ahead in the
<ST_LOOKING_FOR_VARNAME>{LABEL} { rule and detect cases where it should be a 
T_STRING, i.e if the char after it is either } [ or {.

Dmitry, do you think this is okey? 

or should we document this behavior?

Description:
------------
if use '@', you can call function in a string substitution context.

Test script:
---------------
<?php
$la = "ooxx";

$a = "${@substr('laruence', 0, 2)}"; 

echo $a;

Expected result:
----------------
PHP Error: syntax error 

Actual result:
--------------
ooxx
